The intermediate Palomar Transient Factory (ATel #4807) report the discovery of an apparent nova in M31, iPTF14ht, at RA=00:42:23.58, Dec=+41:29:12.4. This optical transient was first detected on UT Jan 18.1, 2014 at magnitude R=19.6, brightened to R=19.0 on UT Jan 20.1, and dropped to R=19.2 on UT Jan 21.1. Nothing was there at this location on UT Jan 13, and previous iPTF images (typically nightly observations), with typical limiting magnitudes R~21 mag. It is in the disk of M31 in the line of sight, and may have large extinction by M31 dust.
